Right now, I have a DSL and an R4. That's it. What are the must-haves for any DSL owner? I'm definitely going to need a screen protector, so please recommend a good one. (Although, Nintendo does advise not to use any non-Nintendo screen protectors...should I just ignore that?) I'd appreciate CHEAP accessories, as I'm definitely not looking to spend a lot of money here. Plus, if they can be found at DX, that would be a plus as I'd like to buy from them.
